I want to set up a robust, flexible 12v power system for my '77 K5 Blazer. Currently, the details I have in mind:
-Deep-cycle marine battery mounted in back bed area
-All radios, gps, toys connected to one 12v power bus
-that 12v bus should be switchable to use either truck battery or deep-cycle as the source
-Some sort of provision for charging/maintaining the deep cycle battery
-Some way to 'emergency' jump start the truck off of the deep cycle without removing the battery
-Undesired current control (am I looking at fat diodes to stop the deep-cycle from 'powering' the truck when not wanted?)
What would be the best way to go about this? I would imagine that somebody's come out with a 'little black box' to allow an additional battery for vehicle electronics - anything on the market, or is this a homebrew setup?
